It provides a fixed 5 V output with ±0.5% initial tolerance, suitable for biasing ADCs, DACs, or setting a stable reference rail in mixed-signal and power-management circuits. ## Noise, drift, and cathode current — the parametric floor Minimum cathode current is 95 µA, and the shunt can sink up to 15 mA. The designer sizes the series resistor so the cathode current stays above 95 µA at the minimum supply voltage and below 15 mA at the maximum supply — standard shunt reference biasing. ## Through-hole TO-92-3 package — mounting and footprint The part comes in a TO-226-3 / TO-92-3 package with formed leads, intended for through-hole PCB mounting.","metaTitle":"LM4040C50ILPR Shunt Voltage Reference, 5 V ±0.5%, TO-92-3","metaDescription":"Texas Instruments LM4040C50ILPR precision 5 V shunt reference, ±0.5% tolerance, 80 µVrms noise, -40°C to 85°C, TO-92-3 through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Cut Tape (CT); Tape & Box (TB)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA) Formed Leads","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"95 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"80µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3990","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040C50ILPR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040C50ILPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040C50ILPR when reusing this data.
